Guys, I'm thinking on getting a new computer. I chose the iMac 27". The problem is that it uses, yet, C2D instead of new architectures with Core ix. I need a computer to last me for a long time and I don't know if I should wait or not. The model I want is the base model of the 27" iMacs. What do you think? Should I go for it anyway or (try) to wait? The thing is that the new computer is not that urgent but It would be useful.
